German soldiers found entombed in a perfectly preserved World War One shelter

Twenty-one German soldiers entombed in a perfectly preserved World War One
shelter have been discovered 94 years after they were killed. The men were
part of a larger group of 34 who were buried alive when a huge Allied shell
exploded above the tunnel, near the small town of Carspach in the Alsace
region in France, in 1918 causing it to cave in.
